中文摘要:
      利用船载CTD仪、国外剖面浮标(APEX)和实验室盐度计等标准仪器设备,在西北太平洋海域对2种型号国产剖面浮标(COPEX和HM2000)进行了现场比测试验,并对观测资料质量进行了定性和定量分析与评价。结果表明:(1)COPEX和HM2000型剖面浮标观测的盐度资料均能达到国际Argo计划提出的±0.01的精度要求;(2)HM2000的最小观测深度离海面1 dbar以内,最大观测深度基本稳定在2000 dbar左右,并能保持在1000 dbar深度附近漂移,而COPEX的最小观测深度在8-9 dbar之间,最大观测深度则在1800-1900 dbar之间波动,且漂移深度都在600-800 dbar之间;(3)COPEX和HM2000都获得了70条以上有效观测剖面。总体而言,两种国产剖面浮标观测的温、盐度资料都是可信、可靠的。但试验中暴露的一些问题和不足仍有待不断改进和完善。
英文摘要:
      Using shipborne CTD, imported profiling buoy (APEX) and laboratory salinometer and other standard instruments, the on-site comparative testing is carried out in the northwestern Pacific Ocean on two models of domestic profiling buoys (COPEX and HM2000), and the quality of observation data is analyzed and evaluated in a qualitative and quantitative manner. The results indicate that (1) the salinity data observed by the COPEX and HM2000 buoys can meet the accuracy requirement put forward by the International Argo Plan (±0.01); (2) for HM2000, the minimum observing depth is between 0 and 1 dbar, and the maximum observing depth stays at 2000 dbar, with the drifting depth of about 1000 dbar; for COPEX, in contrast, the minimum observing depth is between 8 and 9 dbar, the maximum observing depth fluctuates between 1800 and 1900 dbar, with the drifting depth between 600 and 800 dbar; (3) both COPEX and HM2000 can get more than 70 effective observing profiles. In general, the temperature and salinity data of the two kinds of domestic profiling buoys are both believable and reliable. However, the problems exposed in the testing remain to be tackled through continued improvement.
